The Question
On the other side of the power levels scale we have The Question AKA Vic Sage. Created by Spider-Man co-creator Steve Ditko in 1967, The Question is a private investigator turned vigilante who hides his face with an artificial skin. Though the character served as the inspiration for Rorschach in Watchmen, the vigilante hasn’t got many adaptations under his belt, despite a lot of fans calling for it. If Legends ever wanted to do a noir-ish episode, with a hard-boiled detective operating in a corrupt city, The Question would be perfect to adapt.
Alternatively, it could be a good idea to tackle the modern incarnation of the character; Renee Montoya, a Gotham cop who’s mentored by Sage to become The Question. You might think that Montoya’s role in Gotham would prevent the character from hopping over to the Arrowverse, but actually, both the Dollmaker and – more notably – Ra’s al Ghul have featured in both Arrow and Gotham before.
